1918 | June 12

On 12 June, 1918, the U.S. submarine chasers assigned to Base 25 engaged in their first hunt. From Hunters of the Steel Sharks: The Submarine Chasers of WWI:

"A classified document circulated to the commanding officers of the chasers, No. 1: - Routes to Stations, provided precise instructions to their assigned locations, including the bearings and runs that would bring each chaser to its spot on the line, and a graphical depiction of the routes on a rough nautical chart marked in a numbered gridwork."
